However, it may reconstruct invalid call stacks in some cases, e.g. exception handing such as setjmp/longjmp. Also, it may impact the processing time especially when the number of samples with stitched LBRs are huge. Add an option to enable the approach.

Like the GTT pwrite path fix, this uses an optimistic path and a fallback to get_user_pages. Note that this means we have to stop using vfs_write and roll it ourselves.
